Hello to the list, from a lurker, supposedly retired, but....
having run across one last MVIII crate for a lowly buck,
in surplus..... you know the rest. It just has to run some
form of ancient BSD again.....(:+}}.....
Anyway, it is sans tape, and all my TK50 cartridges have
decomposed to dusty oxide, so it will have be resurrected
from something other than tape.
As luck has it, it has a scsi controller, and I happened to
have a scsi floppy from a decishbox long since gone to
the great bit crusher in the sky. So, with some prodding
it booted off a NetBSD 1.4.1 vax floppy and was made
to run NetBSD 1.4.3 as a starter, to get the rest of the
early BSD bits onto the machine. After making fsck trip
all over itself, and pushing some Tahoe and Reno bits
onto it, it now RUNS Tahoe (q0c variety) or Reno (archive
variety) quite happily.
The problem is that it won't install boot blocks that work.
None of the raboot/rdboot/bootra/bootrd combos get
any farther than the cryptic "loading boot" message.
The machine locks up hard then. Yet, I can boot and run
things fine off a NetBSD 1.1A VAX tk50 boot file ("stand")
dd'd to that lonely scsi floppy off the far end of the bus,
with the usual b/3 duaX.... followed by "ra0a" as the root
and ^D to multiuser baby. Years ago, the first time around,
I had this working fine, but, when I backed up the then
running system, I forgot (like a dummy) to dd off a set of
working boot blocks or a working bootable root. Ahh, stupid
me.....(:+}}.....
The nearest that I can tell is that it is not writing (using the
disklabel executable) a correct set of block addresses to
find the real /boot and kernel. Once, however done, the
kernel is actually loaded, it runs fine (like off NetBSD tape
boot "stand").
Any of you old timers got any thoughts as to where my suite
is going afoul of the real way? It is probably something quite
simple, but, my greymatters just can't seem to get it figured
out. Any insights are appreciated.
Thanks!

Linux is very unlike early v[567] kernels. Those kernels are not
posix by any stretch of the imagination. In addition, Posix is a
userland interface, not an internal kernel structure, so even if they
were posix, I'm not sure how much it would help you. Porting Linux's
usb stack to FreeBSD, say, would be really hard because Linux and
FreeBSD have such different intenral kernel APIs.
You'll also run into the size issue if you want to implement a generic
stack. For example, FreeBSD's usb stack is 100kB. While one could
slim that down a lot (it include multiple drivers and such), it would
be difficult to fit in the space contraints of the PDP-11 It should
be possible, but one's first naive attemept to implement things may
not be so straight forward.

this name `internet' name space was considered and rejected. it's
harder than one would think to get details right for all networks, the
addess is only a small part of the information needed for the
connection, and keeping a name space for all the internet updated
would be very hard. instead they use a network!machine!port syntax
with the dial command.
you can follow the full development of those ideas in the following papers.

Waddayamean?
I mean: what does it mean to you 'the spirit of
ancient
Unix'?
If by that you mean the fact that they were simple,
slim and efficient, doing one simple thing and doing
it right, you may then consider the effort by
ast in the 80's with MINIX. OK, it used it's own
microkernel, but the basic idea is the same... and has
been followed on by Mach, BSD-lites, Flex, MacOS X,
Tru64, Linux on L4, etc...
As a matter of fact I always felt UNIX after v7 got it
wrong: e.g. network data is no longer another stream
(I'd have loved it to be a file system with
directories
representing network addresses and ports being files
or
pipes). Thus, later unices increased complexity by
abandoning the simlicity of the original design. If
that is the case, Plan 9 is a good update. And so is
Inferno.
Actually, I always felt that many additions to UNIX
might have been better implemented outside the kernel
if only the kernel had been expanded to allow
user-mode
expansions. But that's already here with kernel
modules
in Linux, BSDs, Solaris, etc... which are becoming
more
and more microkernelized each day. As microkernels
become bigger :-)
OTOH, if you mean adding 'modern' services, perhaps
QNX
is doing it with its support for Real-time. Or adding
dynamic libraries, networking, modern virtual memory
(beyond swapping), etc... which at the plainest level
is what more or less likeably all modern UNIX have
done.
Extending into the future? Distributed computing,
clusters, etc? Like some commercial UNIX, Amoeba,
Inferno and the like?
If you only mean resurrecting these ancient UNIX on
modern hardware, there have been initiatives to
rewrite
v7 alike systems for other architectures (say OMU,
UZI,
MINIX, Coherent, Xinu, etc.). But for that you already
have emulators that provide you the original flavor at
even higher speeds in a virtualized environment.
So? waddayamean?
I think the answer to your question is YES! Lots of
people have tried to improve ancient UNIX more or less
successfully, and many people is still trying, using
microkernels, no-kernels, adding RT, VM, dynamic
libraries, kernel modules, etc... Each with their own
approach.
This said, if I were to pick an initiative that gets
closest to the wishes of the original designers, that
should undoubtedly be Plan 9 and its successor,
Inferno, as they are what the 'Original Designers'
themselves have done when they tried to repeat it
doing
it 'right' (or at least better) no matter what my
personal opinions regarding the issue may be.
Regarding my opinion, yes, I would go for the good old
leather-bound days of IBM mainframes with MVS. (zOS?)
which oddly enough are finally reaching the rest of us
with Xen and emulators like QEMU. If I were to wish,
I'd like a no-kernel approach (everything independent,
cooperating, hot-substitutable, fully migratable
processes) over a virtualizing system that allows me
to
run several OSs and update/change any OS component on
the fly without service interruption, and to migrate
everything between machines on demand ('cos of
overload
or hw failures or whatever, or just 'cos I wish to).
Now, _that_ would IMHO be close to ultimate OS design:
something that can always be updated on the fly and
may
survive any change, something that can adapt and
evolve
without interruption or even the user noticing. But
that is a complex enough concept to expect most system
programmers to grasp, let alone sysadmins, programmers
or users not to pervert. Not to talk of salesmen and
marketroids!

Plan 9 is to UNIX as SVr4.2.2.2.2.2.2 is to Sixth Edition.
If that's the spirit of the modern age, give me the good
old leather-bound days, without all that modern rhythm-
type dancing and hooting and waving.
